How to Test a Pool Pump Capacitor: 4 Easy Steps
Always replace a bad capacitor with a model that has the same voltage. If you must, always use one with a slightly higher voltage. Never use one with a lower rating. Reconnect the motor leads to the replacement capacitor and fasten the capacitor in place as required. Use a multimeter to verify if the capacitor is in good working condition.
Filter Capacitor
How filter capacitors work is based on the principle of capacitive reactance. Capacitive reactance is how the impedance (or resistance) of a capacitor changes in regard to the frequency of the signal passing …
